(PhysOrg.com) -- An unexpected discovery by UCLA life scientists holds promise for the future development of treatments for post-traumatic stress disorder and other anxiety disorders, and potentially for Alzheimer's disease and other memory-impairment diseases. http://phys.org/news213607174.html Medicine & Health Fri, 07 Jan 2011 07:20:07 EST news213607174 Normally, cortical nerve cells or neurons reside in the brain's gray matter with only a few scattered neurons in the white matter, but some people with schizophrenia have a higher number of neurons in the white matter. Neuronal migration errors may arise in schizophrenia as a consequence of both genetic and environmental factors. http://phys.org/news213360908.html Medicine & Health Tue, 04 Jan 2011 10:55:23 EST news213360908 Ever wonder why it's such an effort to forget about work while on vacation or to silence that annoying song that's playing over and over in your head? http://phys.org/news204220333.html Medicine & Health Mon, 20 Sep 2010 17:30:08 EST news204220333 UCSF scientists report that they were able to prompt a new period of "plasticity," or capacity for change, in the neural circuitry of the visual cortex of juvenile mice. The approach, they say, might some day be used to create new periods of plasticity in the human brain that would allow for the repair of neural circuits following injury or disease. http://phys.org/news188745701.html Medicine & Health Thu, 25 Mar 2010 14:23:11 EST news188745701 Imagine that you're working on your back porch, hammering in a nail. Suddenly you slip and hit your thumb instead — hard. The pain is incredibly intense, but it only lasts a moment. After a few seconds (and a few unprintable words) you're ready to start hammering again. http://phys.org/news169403390.html Medicine & Health Thu, 13 Aug 2009 17:32:13 EST news169403390 Some people who take the fast-acting sleep-aid zolpidem (Ambien) have been observed walking, eating, talking on the phone and even driving while not fully awake. Many often don't remember doing any of these activities the next morning. Similarly, this drug has been shown to awaken the minimally conscious into a conscious state. A new study by Georgetown University Medical Center (GUMC) researchers may help explain why these "awakenings" occur. http://phys.org/news165515751.html Medicine & Health Mon, 29 Jun 2009 17:36:31 EST news165515751 New research reveals a sophisticated brain mechanism that is critical for filtering out irrelevant signals during demanding cognitive tasks. The study, published by Cell Press in the February 26 issue of the journal Neuron, also provides some insight into how disruption of key inhibitory pathways may contribute to schizophrenia. http://phys.org/news154787315.html Medicine & Health Wed, 25 Feb 2009 12:29:21 EST news154787315
